QMainWindow MousedBubleclicekevent替代不起作用

Question

我正在使用下面的代码来尝试捕获主窗口中的双击”

import sys
from PySide6 import QtCore
from PySide6.QtWidgets import (
    QApplication,
    QGridLayout,
    QMainWindow,
    QSplitter,
    QTreeView,
    QWidget,
)
from PySide6.QtWebEngineWidgets import QWebEngineView


class MainWindow(QMainWindow):

    def __init__(self):
        super().__init__()

        self.windowLayout = QGridLayout()
        self.splitter = QSplitter()

        self.webView = QWebEngineView()
        self.webView.setUrl(QtCore.QUrl("http://127.0.0.1:8080"))
        self.tree = QTreeView()
        self.splitter.addWidget(self.webView)
        self.splitter.addWidget(self.tree)
        self.windowLayout.addWidget(self.splitter)

        self.mainWidget = QWidget()
        self.mainWidget.setLayout(self.windowLayout)
        self.setCentralWidget(self.mainWidget)

    def mouseDoubleClickEvent(self, e):
        print('test')


if __name__ == "__main__":
    app = QApplication(sys.argv)

    window = MainWindow()
    window.resize(1500, 1000)
    window.show()

    app.exec()

并且我得到以下控制台输出：

qt.pointer.dispatch: delivering touch release to same window QWindow(0x0) not QWidgetWindow(0x600003bb8e40, name="MainWindowClassWindow")
qt.pointer.dispatch: skipping QEventPoint(id=1 ts=0 pos=0,0 scn=749.346,451.159 gbl=749.346,451.159 Released ellipse=(1x1 ∡ 0) vel=0,0 press=-749.346,-451.159 last=-749.346,-451.159 Δ 749.346,451.159) : no target window

但是，当我注释掉 self.setCentralWidget(self.mainWidget) 时，我显然不知道没有看到任何内容，但双击会触发。

编辑：更新为最小重现，另请注意，单击 QWebEngineView 内以外的任何位置都会导致 mouseDoubleClickEvent 触发。我单击 QWebEngineView，但当我单击 QTreeView 内部时没有任何反应

根据Musicamante的非常有用的评论（请参阅原始帖子），我最终使用的解决方案是

...
     self.tree.doubleClicked.connect(self.treeDoubleClicked)
...
def treeDoubleClicked(self, index):
     self.selectedFilepath = index.model().filePath(index)
